Hi,
I can do this job and have it done on a few hours. I have more than 5 years of experience working with DigitalOcean droplets.
-- First I will create a Droplet on your DO account, or you can provide its access.
-- I will set it up to use the required software for Sharetribe (ruby, mysql, apache, etc)
-- Then I will install it and get it ready so you can work on it.
